The New York Knicks have lost their starting center for 20 games for taking a banned substance.

The suspension will start when Noah — who has not played since Feb. 4 and had arthroscopic surgery on his left knee Feb. 27 to remove loose fragments of cartilage or bone — is “eligible and physically able to play” in either a regular season or playoff game, the NBA said. The suspension would then carry into the 2017-18 season.
